Kuhl Control.
Rugged, easy-to-use controls let you customize or keep it simple
Kuhl has four operating modes that put full control in your hands, from manual to energy-saving 7-day programmable settings.
Manual: Use the unit controls or remote to turn the unit on and off and to adjust the temperature.
7-day Default Program: Pre-set to ENERGY STAR® recommendations. Optimizes energy saving at night when the building is unoccupied.
7-day Custom Program: Set up to four comfort settings per day and a shut-off option when the building is unoccupied.
Wired to a wall thermostat: For hard-to-reach installations or spaces with hot spots. The wall thermostat operates the unit and overrides the unit control panel.
For additional energy management and cost control, the LCD lockout feature prohibits occupants from changing your desired temperature setting.
To ensure long-term ease of use and durability, we put the electronic controls through rigorous testing.

Kuhl Efficiency
From programmability to the refrigeration system, Kuhl is designed to reduce energy consumption.
Auto Fan mode saves money by conserving energyENERGY STAR®-qualified models, including all four heat pumps24V low-voltage interface for wall thermostat or energy management controlEnvironmentally-friendly R-410A refrigerant used in all modelsHigh-tech rifled copper tubing and slit fins have greater surface area for maximum heat-exchange efficiency.Kuhl Quiet
Gaps, insufficient insulation, and improperly mounted moving parts can contribute to operational noise. We designed Kuhl to minimize noise-causing vibration, outdoor noise intrusion and operating noise, while maintaining optimal air flow. Every unit has these important noise-reduction features:
Motor mount: The dual resilient rings prevent the metal-to-metal contact that causes noise and vibrationHigh-efficiency compressors: Mounted on extra-thick rubber grommets that absorb vibrationSolid-steel blower wheel housing: Provides maximum sound reductionSteel inner wall, insulated plenum, heavy-duty hardboard side panels and extra dense insulation: Blocks outdoor noiseAir discharge: Wider openings and better airflow design minimize airflow noiseKuhl Purity.
Kuhl's advanced dual-stage filtration system removes allergens, odors, ozone and other impurities from the air. By combining the optional carbon filter with the standard antimicrobial filter, Kuhl achieves lab-tested superior air filtration with ratings as high as MERV 6. Use the fresh-air vent and the exhaust vent for additional air-quality control.
When both vents are closed, Kuhl cleans and conditions the air in your space. Open the fresh-air vent and Kuhl purifies and conditions a moderate amount of outdoor air along with the air in your room. Use the exhaust vent to release stale air and odors outside.
Kuhl Comfort.
The most comfortable temperature is the one you never notice. Kuhl uses five built-in environmental sensors to more accurately monitor indoor and outdoor temperatures so that it can maintain your ideal settings.
Kuhl+ models have the ability to cool or heat as needed so units can operate as year-round central systems. And, like the most advanced central systems, Kuhl+ has auto-changeover, which allows the unit to automatically switch between air conditioning and heating functions to maintain the desired comfort level. You won't have to lift a finger.
Plus, Kuhl's air flow systems are tested for powerful and precise air distribution which means faster cooling when you need it most.
Kuhl Testing.
Rigorous testing, ongoing quality control
Before Kuhl hit the market, we carried out a punishing battery of tests in a UL-certified lab. We continue to test, refine and improve because our commitment to quality and to our customers demands it.
